ORX-005 (RX-05S) "Hawkbi" / ORX-005 (TR-05S) "Hawkbit"
I was going for something like HGUC ORX-005 Gaplant TR-5 (Hrairoo), but with more of a MSZ-009H Fafnir style. Essentially going the Hyaku Shiki route and and changing focus to a more general purpose MS. Though the side shield boosters with beam rifles were kept to add additional mobility and "area dominance".
My OC UC lore (plenty of cringe, but atleast it's 100% not AI, so it has that going for it):
Developed by Titan Test Team, to be a cyber-newtype platform for testing psycommu deployed weapons systems, the "Hawkbit" was assigned to the "Enhanced Human" Ensign Eris(my OC self insert, do not steal, lol). During her first conflict she felt negative pressure feedback from a mission in Side 1, pressure screaming at her to stop, like the ghost from an entire colony(the G3 gassed colony to be specific), and using the boosters-shields she left the field of conflict, screaming; officially considered AWOL by the Titans, which was quickly changed to traitor when she started picking off low defended Titan targets and then disappearing just as fast as she arrived. Driven by the screams of the dead, she made these strikes until the Titans disbanded; upon which she then turned herself into the Feddy forces, with no memory of who she was, she arrived in the "Hawkbi" (which had the "T" angrily scratched off with a field-issue knife) asleep and malnourished. Her and her MS were rolled into the EFF Cyber Newtype group, and both classified top secret, The "Hawkbit" re-named/flagged the RX-05S "Hawkbi". She seems very happy, polite, and curious; but at night she still screams, screams only known from horrors beyond thinking understood by a newtype's ability to know the true cost of war. She now leads a EFF Team with an oldtype veteran who's career started as a OYW GM pilot, and they never stopped piloting, a true old salt who knows how to keep the sometimes clueless cyber-newtype they're assigned to alive when they need it.
(anyone else like to imagine deep lore for their creations, that fits with existing cannon lore?)
Gameplay wise, this MS is a beast, and can solo newtype easily; with missle spamming, beams, and full burst that can 1-shot most enemies even on newtype difficulty. Also has an I-field, Chobin armor, nuke sheild. Very fun to play, but will make any lower dificulty laughable.
